### Check page does not automatically refresh without warning or options

<div id="locLevel"></div>

Page should not automatically refresh without warning or option to turn it off or adjust the time limit

</Column>
</Row>
<Row>
<Column colLg={11} colMd={5} colSm={4} className="toolMain">

### Why is this important?

Unexpected automatic page refresh within a short time interval without an option to turn it off or adjust the time limit, can disorient people and prevent them from reading or finishing the task at hand.

<div id="locSnippet"></div>

### What to do

* If the time limit is required or essential, no action is needed;
* OR, provide an option to allow the user to turn auto-refresh off;
* OR, allow the user to adjust or extend the time limit and warn them before it expires;
* OR, set the time limit longer than 20 hours.
